Qt Group has released Qt 6.12, its latest long-term support (LTS) version, which comes with a five-year maintenance plan and the first EU Cyber Resilience Act (CRA) declaration of conformity for Commercial Qt. This release introduces significant features such as native QML hot reload, allowing developers to patch changes in place without reloading the entire scene, and a GPU-accelerated Canvas Painter that has moved out of Technology Preview. Additionally, Qt 6.12 includes support for HarmonyOS and offers numerous improvements across various functionalities, making it a solid choice for developers working on proprietary products in compliance with upcoming EU regulations. Although the release is not packed with flashy new features, it emphasizes security, rendering, and tooling enhancements, making it a pragmatic choice for long-term production use

Qt 6.12 LTS Released: First CRA Compliance and QML Hot Reload

Qt Group shipped Qt 6.12, its newest long-term support release with five years of maintenance and a first-ever EU Cyber Resilience Act declaration of conformity for Commercial Qt. The LTS makes the framework a safer default for proprietary products heading into the EU's December 2027 CRA deadline, though the signed declaration only covers Qt's portion of compliance. Developers get native QML hot reload that patches changes in place instead of reloading the whole scene, plus a GPU-accelerated Canvas Painter now out of Technology Preview. The release also adds HarmonyOS support and a long tail of improvements across networking, Lottie, and the build system, and is available now through the Qt installer.
